  • Quality of Cluster Index Based on Study of Decision Tree
    validity indices are geometry based cluster quality measures This work proposes a cluster validity index based on the decision theoretic rough set model by considering various loss functions Real time retail data show the usefulness of the proposed validity index for the evaluation of rough and crisp clustering The measure is shown to help determine optimal number of clusters as well as an important parameter called threshold in rough clustering The experiments with a promotional campaign for the retail data illustrate the ability of the proposed measure to incorporate financial considerations in evaluating quality of a clustering scheme This ability to deal with monetary values distinguishes the proposed decision theoretic measure from other distance based measures Our proposed system validity index can also be efficient for evaluating other clustering algorithms such as fuzzy clustering References Cited By J C Bezdek Pattern Recognition with Fuzzy Objective Function Algorithms Plenum Press 1981 doi 10 1007 978 1 4757 0450 1 5 D L Davies and D W Bouldin A Cluster Separation Measure IEEE Trans Pattern Analysis and Machine Intelligence vol 1 no 2 pp 224 227 Apr 1979 doi 10 1109 TPAMI 1979 4766909 J C Dunn Well Separated Clusters and Optimal Fuzzy Partitions J Cybernetics vol 4 pp 95 104 1974 doi 10 1080 01969727408546059 S Hirano and S Tsumoto On Constructing Clusters from Non Euclidean Dissimilarity Matrix by Using Rough Clustering Proc Japanese Soc for Artificial Intelligence JSAI Workshops pp 5 16 2005 T B Ho and N B Nguyen Nonhierarchical Document Clustering by a Tolerance Rough Set Model Int l J Intelligent Systems vol 17 no 2 pp 199 212 2002 doi 10 1002 int 10016 Rough Cluster Quality Index Based on Decision Theory Pawan Lingras Member IEEE Min Chen and Duoqian Miao IEEE TRANSACTIONS ON KNOWLEDGE AND DATA

  • Query as Region Partition in Managing Moving Objects for Concurrent Continuous Query
    10 7815 ijorcs 21 2011 008 Close Abstract Applications in location based services rely on the efficient management of large scale moving objects and one of the most important operations is real time continuous query over moving objects such as monitoring the objects of a certain region In order to satisfy the high throughput and handle real time updates and queries it is a good choice to introduce multi core parallel processing and managing spatial indices in main memory In this paper we propose a new scheme of processing continuous query on a novel spatial index based on uniform grid which is proved to be a good indexing scheme in main memory The novelty of our index is to manage query region as the partition in the spatial index which unified the index updating and query processing Our experiments indicate that this sophisticated approach has better performance especially when the query is rather stationary References Cited By Volker Gaede Oliver G unther Multidimensional Access Methods In ACM Computing Surveys CSUR Volume 30 Issue 2 June 1998 doi 10 1145 280277 280279 D Kalashnikov S Prabhakar S Hambrusch Main Memory Evaluation of Monitoring Queries Over Moving Objects Distributed and Parallel Databases An International Journal Vol 15 No 2 pages 117 136 2004 doi 10 1023 B DAPD 0000013068 25976 88 Maurice Herlihy and Nir Shavit The Art of Multiprocessor Programming Elsevier 2008 Hector Garcia Molina Jeffret D Ullman Jennifer Widom Database System Implementation Second Edition Pearson Education Inc 2009 Darius ˇ Sdlauskas Simonas ˇ Sltenis Christian W Christiansen Jan M Johansen Donatas ˇ Sulys Trees or Grids Indexing Moving Objects in Main Memory In ACM GIS 09 November 4 6 2009 Seattle WA USA Hanan Samet Foundations of Multidimensional and Metric Data Structures Morgan Kaufmann Publishers 2006 John T Robinson The K D B Tree A Search Structure for Large Multideminsional Dynamic Indexes In Proceedings of the ACM SIGMOD International conference on Management of data 1981 Diane Greene An Implementation and Performance Analysis of Spatial Data Access Methods In Proceedings Fifth International Conference on Data Engineering 1989 doi 10 1109 ICDE 1989 47268 Antonin Guttman R trees a dynamic index structure for spatial searching SIGMOD Rec 14 2 June 1984 47 57 doi 10 1145 971697 602266 Xiaopeng Xiong Mohamed F Mokbel etc Scalable Spatio temporal Continuous Query Processing for Location aware Services In Proceedings of 16th International Conference on Scientific and Statistical Database Management 2004 SSDBM04 Jing Dai Chang Tien Lu CLAM Concurrent Location Management for Moving Objects In ACM International Symposium on Advances in Geographic Information Systems New York NY USA 2007 Chang Tien Lu Jing Dai Ying Jin Janak Mathuria GLIP A Concurrency Control Protocol for Clipping Indexing IEEE Transaction on Knowledge and Data Engineering Vol 21 No 5 2009 doi 10 1109 TKDE 2008 183 Jing Dai Chang Tien Lu Lien Fu Lai A Concurrency Control Protocol for Continuously Monitoring Moving Objects In Tenth International Conference on Mobile Data Management Systems Services and Middleware 2009 doi 10
